Explanation:
they are located in the neucleus
Answer:
82.1
Explanation:
Isotopes of the same element are atoms of the same element (so, having same number of protons) having a different number of neutrons (and so, a different atomic mass).
In this problem, this element has 3 different isotopes, with atomic mass (in atomic mass units, a.m.u.) and relative abundance listed below:
1) 78.9 12.6%
2) 80.9 13.9%
3) 82.9 73.5%
In order to calculate the relative atomic mass unit of this element, we have to calculate the weighed average of the relative atomic mass of each isotope.
This means that we can calculate it as the sum of each atomic mass unit multiplied by the relative frequency:

where
is the atomic mass of each isotope and
the relative frequency. Therefore, we find:

Answer:
C.
Milk boils at about 212°F (100°C).
Explanation:
The boiling point is a physical property of every matter. Physical properties tell us what a substance is when no change is occuring to its constituents. Such properties can be observed with our senses or instruments or pieces of apparatus.
Some examples of physical properties are colour, taste, odour, hardness, texture, solubility in water.
They all depict what typifies a matter when no change whatever is imparted on them.
